Acute mesenteric thrombosis in two patients with COVID-19. Two cases report and literature review.

Introduction: The coronavirus disease 2019 (COVID-19) affects mainly the respiratory system, other organs may be involved, usually due to coagulation disturbances that lead to a high rate of thrombotic complications.

Case Presentation: The first patient is 45 years-old who has been exposed to SARS CoV-2. Upon admission due to acute abdomen evidence surgery is performed in which an intestinal resection with an adequate post-surgical evolution takes place so the patient is discharged after 4 days with a prescription for oral anticoagulants.

Evaluation of C-reactive protein, procalcitonin and the PCR/PCT index as indicators of mortality in abdominal sepsis.

Background: Biomarker combinations can improve timely diagnosis and survival.

Objective: To determine the usefulness of serum procalcitonin concentration (PCT), C-reactive protein (PCR) and the PCR / PCT index as predictors of mortality.

Method: Retrospective study of patients diagnosed with abdominal sepsis during the period from April 2017 to February 2018.

Evaluation of the level of high density lipoproteins as a predictor of severity in abdominal sepsis.

Background: Alterations in the lipid profile are part of the acute phase response, this corresponds to the so-called lipemia of sepsis.

Objective: To determine if the serum level of high density lipoprotein (HDL) is related to severity and mortality.

Method: Retrospective, descriptive, cross-sectional study of patients diagnosed with abdominal sepsis.

Comparison between the body mass index and the Controlling Nutritional status to determine the severity in patients with abdominal sepsis.

Background: The systemic response of the organism, in defense against the aggressor agent, generates acute catabolic response, which leads to deterioration of the nutritional status.

Objective: Compare the usefulness of the body mass index (BMI) and the CONUT scale to determine the severity in abdominal sepsis.

Methods: Retrospective, descriptive, cross-sectional study in patients with diagnosis of abdominal sepsis, from April 2016 to February 2017.

Controversial case: Revascularization of a popliteal vascular injury of poor prognosis.

Introduction: Popliteal injuries are significant health risk that could induce permanent functional impairment, limb loss, and in some cases death. Currently, there is a controversy about the required treatment between amputation and a limb salvage surgery, which in some cases could cause more prominent functional impairment than the amputation. Different indicators help to predict, in some extent, the risk of amputation, however most of them were described two decades ago.

Minimally invasive therapy for epiphrenic diverticula: Systematic review of literature and report of six cases.

Introduction: Epiphrenic diverticula (ED) are infrequent and conventional surgical treatment entails aggressive open or transthoracic surgery. Minimally invasive treatment has changed the surgical approach but some surgical controversies are not resolved.

Objective: The objective of this study is to describe our experience in minimally invasive treatment of the ED and to perform a systematic review of the current literature in this subject.
